Jack,

Try to stay on point. We are not talking exclusively about bat-speed. We are talking about
Major League swings and how they are created. Why do you deny that linear/directional
forces are applied to the Major League swing?

I agree with you that rotational forces supply more power and bat-speed to the swing, but
why do you disagree with me that rotational forces along with linear/directional forces are
the combination that quality swings contain.
